Attempting true 1080p XBMC output on AML-8726 (CMX) device

[nothome]

Trying to get kernel and XBMC running at 1080p. Managed to get it working with one cavet. Other than playing video, screen is only showing 1280x1080, right hand side of the screen is black. But when I play a 1080 video in XBMC, it plays in full 1920x1080. Difference quality is obvious. Also getting full 23 fps.

What I did so far to achieve it is,
Run SSHDroid on the device.
Connect PC to device over ssh and,

# su
# cd /
# mount -o rw,remount /system
# vi /system/build.prop
Changed two lines to look like,
const.window.w=1920
const.window.h=1080

Also commented out following line (although I don't think it made any difference)
#ro.platform.has.1080scale=2

Then exit out of vi.
# mount -o ro,remount /system

Power cycle the device.

On next power up, everything is zoomed in. SSH to the device again and,

# su
# echo 0 > /sys/class/graphics/fb0/free_scale
# echo 0 > /sys/class/ppmgr/ppscaler

Now screen should display something close to 1280x1080, rest is black. Same is for XBMC UI. But video play in XBMC is full 1920x1080. You can also confirm that by running "cat /proc/kmsg". when video plays, it will report exact resolution.

You can also switch back and forth between 720 and 1080 by doing "echo 0 > /sys/class/ppmgr/ppscaler" or "echo 1 > /sys/class/ppmgr/ppscaler"

Next, I'll try to fix the partial black screen or maybe try changing xbmc so it will run at 1080 while kernel stays at 720.

I wonder if you ever got this to work? I'm having the same exact issue.
